For example, for FDD, the network device configures uplink frequency domain resources and downlink frequency domain resources for the terminal device respectively, which is a paired spectrum (paired spectrum), and the terminal device Data can be transmitted on both uplink frequency domain resources and downlink frequency domain resources without indicating the time domain resource transmission status. The specific time domain resource transmission status refers to whether uplink data or downlink data is transmitted on the time domain resources, or No data is transmitted, such as for uplink and downlink handovers, etc. In this case, the terminal device uses the uplink frequency domain resource or the time domain resource that the downlink frequency domain resource is not used for data transmission as the unknown time domain resource; for TDD, the network device is The terminal equipment allocates frequency domain resources, which are unpaired spectrum (unpaired spectrum), wherein the frequency domain resources can be used to transmit both uplink data and downlink data, whether to transmit uplink data or downlink data, or not transmit data.

Based on the communication architecture shown in FIG. 1 , the method for determining time domain resources according to the embodiment of the present application will be specifically introduced below.

As shown in FIG. 2 , the method for determining time domain resources in this embodiment of the present application includes:

Step 201, the network device sends indication information to the terminal device, wherein the indication information is used for the format of the time slot.

The indication information in this embodiment of the present application may be sent to the terminal device through physical layer signaling, such as layer 1 (layer 1, L1) signaling, or may be sent to the terminal device through layer 2 (layer 2, L2) signaling, such as media access control (media access control). control, MAC) signaling, or layer 3 (layer 3, L3) signaling, such as radio resource control (radio resource control, RRC) signaling, is sent to the terminal device, or it can be communicated with the terminal device through the network device. other signaling is sent to the terminal equipment, which is not limited.

It should be noted that the format indicated by the indication information in this embodiment of the present application may be the format of N time slots in a certain time period, or may be the format of the time slot used by the current terminal device to transmit data. This is not limited. The format of the time slot indicated by the specific indication information can be determined by the terminal device according to a pre-configured policy, where the pre-configured policy can be sent by the network device to the terminal device, or it can be the terminal device. The device is configured at the factory.

Specifically, the indication information in the embodiment of the present application may be slot format information (slot format information, SFI), for example, the slot format information includes status information transmitted on each symbol in the slot, and the like.

In order to save the signaling overhead of the indication information, optionally, the indication information in this embodiment of the present application may be an index number, where the index number corresponds to the format of the time slot, or, optionally, the indication information directly indicates the format of the time slot .

For example, the format of the time slot includes the number of uplink symbols and the number of downlink symbols, wherein the positions of the uplink symbols and the positions of the downlink symbols are preconfigured, or the determination rules for the positions of the uplink symbols and the downlink symbols are preconfigured; For another example, the format of the time slot includes the number and position of uplink symbols, and the number and position of downlink symbols; for another example, the format of the time slot includes the position and/or number of unknown symbols; for example, the format of the time slot Including the number of uplink symbols, the number of downlink symbols, and the number of unknown symbols, where the positions of uplink symbols, downlink symbols, and unknown symbols are pre-configured, or the positions of uplink symbols, downlink symbols, and unknown symbols are pre-configured. The rules for determining the location of , are pre-configured; the uplink symbol is used to carry the uplink data, the downlink symbol is used to carry the downlink data, and the unknown can be an unknown time domain resource.

Exemplarily, when the indication information is an index number, a possible implementation manner is: the indication information indicates an index number in the correspondence table of the index number and the format of the time slot, wherein the format of the time slot includes the number of uplink symbols and the number of uplink symbols. Taking the number of downlink symbols as an example, the correspondence table between the index number and the format of the time slot may be as shown in Table 2.

The position of the last symbol starts by N2 consecutive numbers, where N1 is the number of downlink symbols included in the format of the time slot, and N1 is the number of uplink symbols included in the format of the time slot. In the case where the rules for determining the position of the uplink symbols and the positions of the downlink symbols can be pre-configured as the above rules, if a time slot includes 14 symbols, when the indication information is index number 1, the format of the time slot is as shown in Figure 3a , the first 12 symbols are downlink symbols, and the 14th symbol is an uplink symbol.

In another example, the rules for determining the position of the uplink symbol and the position of the downlink symbol can also be pre-configured such that the position of the downlink symbol starts from the first symbol position in the time slot and counts N1 consecutively backwards, and the position of the uplink symbol ends from the end of the downlink symbol. The position of the next symbol from the position of , starts with N2 consecutive numbers, where N1 is the number of downlink symbols included in the format of the time slot, and N1 is the number of uplink symbols included in the format of the time slot. In the case where the rules for determining the position of the uplink symbols and the positions of the downlink symbols can be pre-configured as the above rules, if a time slot includes 14 symbols, when the indication information is index number 1, the format of the time slot is shown in Figure 3b, The first 12 symbols are downlink symbols, and the 13th symbol is an uplink symbol.

In one embodiment, the rules for determining the position of the uplink symbol and the position of the downlink symbol may also be preconfigured such that the position of the downlink symbol starts from the position of the first symbol in the time slot for N1 consecutive numbers, and the starting position of the uplink symbol is the same as that of the downlink symbol. The end position of the downlink symbol is separated by one symbol, wherein N1 is the number of downlink symbols included in the format of the time slot, and N1 is the number of uplink symbols included in the format of the time slot. In the case where the rules for determining the position of the uplink symbols and the positions of the downlink symbols can be pre-configured as the above rules, if a time slot includes 14 symbols, when the indication information is index number 1, the format of the time slot is as shown in Figure 3a , the first 12 symbols are downlink symbols, the 14th symbol is an uplink symbol, and the end position of the downlink symbol is separated from the start position of the uplink symbol by one symbol.

In addition, the correspondence table between the index number and the format of the time slot may also be as shown in Table 3, where the format of the time slot includes the number of uplink symbols, the number of downlink symbols, and the number of unknown symbols.

table 3

Wherein, when the correspondence table between the index number and the time slot format is Table 3, the configuration mode of the determination rule of the position of the uplink symbol and the position of the downlink symbol is the same as the determination rule of the position of the uplink symbol and the position of the downlink symbol in Table 2. The configuration method is similar and will not be repeated here.

In addition, the correspondence table between the index number and the format of the time slot may also be as shown in Table 4, where the format of the time slot includes the number of uplink symbols, the number of downlink symbols, and the number of unknown symbols.

Table 4

Wherein, when the correspondence table between the index number and the time slot format is Table 4, the configuration mode of the determination rule of the position of the uplink symbol and the position of the downlink symbol is the same as the determination rule of the position of the uplink symbol and the position of the downlink symbol in Table 2. The configuration method is similar and will not be repeated here.

In addition, the correspondence table between the index number and the format of the time slot may also be as shown in Table 5, where the format of the time slot includes the position of the uplink symbol and the position of the downlink symbol.

table 5

For example, the 0th to 11th positions in the format of the time slot corresponding to the index number 1 are downlink symbols, and the thirteenth position is an uplink symbol.

It should be understood that the format of the time slot includes the number of unknown symbols, or the format of the time slot includes the position of the unknown symbol, or the format of the time slot includes the number and position of the unknown symbol, or the format of the time slot includes the position and the position of the uplink symbol. The location of the downlink symbols, etc., the specific implementation manner is similar to the format of the time slot, including the number of uplink symbols and the number of downlink symbols, and will not be repeated here.

Step 202, the terminal device determines the unknown time domain resource in the time slot according to the indication information and the frequency domain resource configuration information.

The frequency domain resource configuration information may be sent by the network device to the terminal device. During specific implementation, the network device may send the information to the terminal device through high-layer signaling, such as RRC signaling.

As an example, when the frequency domain resource configuration information indicates that the center frequency of the uplink frequency domain resource coincides with the center frequency of the downlink frequency domain resource, the terminal device determines that the unknown time domain resource is a time slot other than the uplink symbol and the downlink symbol. symbol.

Optionally, the frequency domain resource configuration information may directly indicate that the center frequency of the uplink frequency domain resource and the center frequency of the downlink frequency domain resource overlap, or the frequency domain resource configuration information includes the frequency domain when the network device configures the frequency domain resource for the terminal device. Configuration parameters, such as SCS, bandwidth parameters (such as the bandwidth of uplink frequency domain resources and the bandwidth of downlink frequency domain resources), frequency domain location parameters, etc., the terminal device can determine the frequency domain resource configuration information according to these parameters to indicate the uplink frequency domain resources. The center frequency point coincides with the center frequency point of the downlink frequency domain resources. Specifically, taking the frequency domain resource as BWP as an example, as shown in FIG. 4 , the terminal device can determine the lowest frequency position f1 of the uplink BWP according to the frequency domain position parameter of the uplink BWP, and according to the bandwidth parameter of the uplink BWP and the SCS of the uplink BWP can Obtain the absolute bandwidth value BW1 of the uplink BWP, and then determine the center frequency of the uplink BWP as (f1+BW1/2); the terminal device determines the center frequency of the downlink BWP based on the same method as (f2+BW2/2), where f2 is the downlink The lowest frequency position of BWP, BW2 is the absolute bandwidth value of downlink BWP. If (f1+BW1/2)=(f2+BW2/2), the center frequency of the uplink BWP and the center frequency of the downlink BWP coincide.

It should be understood that when the center frequency of the uplink frequency domain resource and the center frequency domain of the downlink frequency domain resource overlap, the frequency domain resource configured by the network device for the terminal device is an unpaired spectrum. Optionally, the terminal device may also determine that the unknown frequency domain resource is a frequency domain resource with a larger bandwidth among the uplink frequency domain resource and the downlink frequency domain resource.

Taking the indication information as the index number 1 in Table 2 as an example, since the number of downlink symbols corresponding to index number 1 is 12 and the number of uplink symbols is 1, for example, suppose the format of the time slot is shown in Figure 3a, if The bandwidth of the downlink frequency domain resource is greater than the bandwidth of the uplink frequency domain resource, then the unknown frequency domain resource is the downlink frequency domain resource. Further, the unknown time-frequency resource can be shown in Figure 5a, including the 13th symbol and the downlink frequency domain resource. composed of time-frequency resources.

In addition, the unknown time-frequency resource in the embodiment of the present application may be the shaded area shown in FIG. 5b, including the time-frequency resource composed of the 13th symbol and downlink frequency domain resources, and the 14th symbol and other frequency domain resources. time-frequency resources, wherein other frequency-domain resources are part of the downlink frequency-domain resources except the uplink frequency-domain resources. In this case, the unknown time domain resources are the 13th symbol and the 14th symbol, and the unknown frequency domain resources are downlink frequency domain resources and other frequency domain resources.

It should be understood that when the bandwidth of the downlink frequency domain resource is equal to the bandwidth of the uplink frequency domain resource, the unknown frequency domain resource may be an uplink frequency domain resource or a downlink frequency domain resource.

As another example, when the frequency domain resource configuration information indicates that the center frequency of the uplink frequency domain resource does not coincide with the center frequency of the downlink frequency domain resource, the terminal device determines that the unknown time domain resource is a symbol other than the uplink symbol in the time slot and the symbols obtained by taking the union of the symbols other than the downlink symbols in the slot. Taking the format of the time slot shown in FIG. 3a as an example, the symbols other than the uplink symbols in the time slot are the 1st to 13th symbols, and the symbols other than the downlink symbols in the time slot are the 13th and 14th symbols.

It should be noted that, in the embodiment of the present application, the manner in which the frequency domain resource configuration information indicates that the center frequency of the uplink frequency domain resources and the center frequency of the downlink frequency domain resources do not overlap with the frequency domain resource configuration information indicating the center frequency of the uplink frequency domain resources. The manner in which the point coincides with the center frequency point of the downlink frequency domain resource is similar, and details are not repeated here. It should be understood that when the center frequency of the uplink frequency domain resource does not coincide with the center frequency of the downlink frequency domain resource, taking FIG. 4 as an example, (f1+BW1/2)≠(f2+BW2/2).

It should be understood that when the center frequency of the uplink frequency domain resource and the center frequency domain of the downlink frequency domain resource do not overlap, the frequency domain resource configured by the network device for the terminal device is a paired spectrum. Optionally, the terminal device determines that the unknown frequency domain resources include the uplink frequency domain resources corresponding to the symbols other than the uplink symbols in the time slot and/or the downlink frequency domain resources corresponding to the symbols other than the downlink symbols in the time slot.

During specific implementation, when symbols other than uplink symbols and downlink symbols in the time slot are unknown time domain resources, the terminal device determines that the unknown frequency domain resources are frequency domain resources obtained by the union of uplink frequency domain resources and downlink frequency domain resources; When the uplink symbols in the time slot are unknown time domain resources, the terminal device determines that the unknown frequency domain resources are downlink frequency domain resources; when the downlink symbols in the time slot are unknown frequency domain resources, the terminal device determines that the unknown frequency domain resources are uplink frequency domain resources.

As an example, taking the format of the corresponding time slot when the index number is 1 in Table 2 as an example, if the format of the corresponding time slot when the index number is 1 is shown in Figure 3a, the uplink frequency domain resources and the downlink frequency domain resources are: In the case of paired spectrum, when the 1st to 12th symbols are unknown time-frequency resources, the uplink frequency domain resources are unknown frequency domain resources; and for the 1st to 12th symbols are downlink symbols In this case, the downlink frequency domain resources are used to transmit downlink data; the 13th symbol is neither an uplink symbol nor a downlink symbol. Therefore, for the case where the 13th symbol is an unknown time-frequency resource, the uplink frequency domain resources and the downlink frequency domain The frequency domain resource obtained by the union of resources is the unknown frequency domain resource; for the case where the 14th symbol is the unknown time-frequency resource, the downlink frequency domain resource is the unknown frequency domain resource; and for the case where the 14th symbol is the uplink symbol Next, the uplink frequency domain resources are used to transmit uplink data. Wherein, when the format of the time slot is shown in Figure 3a, the unknown time-frequency resource can be the shaded area shown in Figure 6, including the time-frequency resource composed of the 13th and 14th symbols in the time slot and the downlink frequency domain resources. resources, and time-frequency resources consisting of the first symbol to the thirteenth symbol in the time slot and uplink frequency domain resources.

It should also be noted that, in the embodiment of the present application, when the corresponding relationship between the index number and the format of the time slot is as shown in Table 2, the network device does not matter whether the uplink frequency domain resources and downlink frequency domain resources configured for the terminal device are paired spectrum or In the case of unpaired spectrum, any index number can be selected from Table 2 and indicated to the terminal device. After the terminal device receives the index number sent by the network device, it further determines the unknown time according to the index number and frequency domain resource configuration information. Domain resources and unknown frequency domain resources, the specific way of determining unknown time domain resources and unknown frequency domain resources is similar to the way of determining unknown time domain resources and unknown frequency domain resources in FIG. 2 , and details are not repeated here.

In the embodiment of the present application, when the corresponding relationship between the index number and the format of the time slot is shown in Table 3, if a time slot includes 14 symbols, because the network equipment configures the uplink frequency domain resources for the terminal equipment and the downlink frequency domain resources When the resource is an unpaired spectrum, the sum of the number of downlink symbols, the number of uplink symbols, and the number of unknown symbols is not greater than 14, the total number of symbols included in a time slot. Therefore, the network device is configured for the terminal device. When the uplink frequency domain resources and downlink frequency domain resources are unpaired spectrum, when selecting the index number from Table 3, it is necessary to select the sum of the number of downlink symbols, the number of uplink symbols, and the number of unknown symbols is not greater than one The index number of the format of the time slot of the total number of symbols included in the slot, and when the uplink frequency domain resources and downlink frequency domain resources configured by the network device for the terminal device are paired spectrum, the number of downlink symbols, the number of uplink symbols The sum of the number of symbols and the number of unknown symbols is not more than twice the total number of symbols included in a slot (when a slot includes 14 symbols, the double of the symbols included in the slot is 28), that is, In the case where the uplink frequency domain resources and downlink frequency domain resources configured for the terminal equipment are paired spectrum, the network equipment needs to select the number of downlink symbols, the number of uplink symbols, and the number of unknown symbols when selecting the index number from Table 3. The index number of the format of the slot whose sum is not greater than twice the total number of symbols included in one slot.

In the embodiment of the present application, when the corresponding relationship between the index number and the format of the time slot is as shown in Table 4, in the case that the uplink frequency domain resources and downlink frequency domain resources configured by the network device for the terminal device are unpaired spectrum, and the downlink frequency domain resources are unpaired spectrum. The unknown symbol corresponding to the domain resource and the unknown symbol corresponding to the uplink frequency domain resource are the same, and the sum of the number of downlink symbols, the number of uplink symbols and the number of unknown symbols is not greater than the number of symbols included in a time slot. The total number, therefore, when the uplink frequency domain resources and downlink frequency domain resources configured for the terminal equipment are unpaired spectrum, when the network equipment selects the index number from Table 4 to indicate to the terminal equipment, it needs to select the one that satisfies the corresponding downlink frequency domain resources. The number of unknown symbols is equal to the number of unknown symbols corresponding to uplink frequency domain resources, and the sum of the number of downlink symbols, the number of uplink symbols and the number of unknown symbols corresponding to downlink frequency domain resources is not greater than The index number of the format of the slot in the total number of symbols included in one slot. In the case where the uplink frequency domain resources and downlink frequency domain resources configured for the terminal device are paired spectrum, the network device can select any index number from the index numbers shown in Table 4 and indicate it to the terminal device. The index number and the frequency domain resource configuration information determine the unknown time-frequency resource, and the method for determining the unknown time-frequency resource is similar to the method for determining the unknown time-frequency resource in FIG. 2 , and details are not described here.

In this embodiment of the present application, the unknown time domain resource in the time slot can be determined according to the indication information and the frequency domain resource configuration information. Compared with the prior art, no additional signaling is required to indicate to the terminal device the duplex used by the network device. way, which helps to reduce signaling overhead and helps to reduce the complexity of network device configuration.

In addition, since the terminal equipment may only be used to transmit uplink data or downlink data at one point in time, in this case, the terminal equipment switches between the uplink and downlink states, and usually the terminal equipment needs a transition time to perform State switching, the transition time can be called a time switching point, which is used for switching from uplink to downlink, or switching from downlink to uplink. In general, a GP is usually set in the format of the time slot. In order to simplify the implementation, the GP is usually configured between the downlink symbol and the uplink symbol, as shown in FIG. 7 . Therefore, in this embodiment of the present application, in order to simplify the implementation , the GP can be configured in the unknown time domain resource between the downlink symbol and the uplink symbol. Therefore, the unknown time domain resource in this embodiment of the present application needs to include the time domain resource located between the downlink symbol and the uplink symbol. When a GP is set in the slot format, optionally, when the slot format includes the number of downlink symbols and the number of uplink symbols, the position and number of downlink symbols in the format of the time slot indicated by the pre-configuration indication information When the position of the uplink symbol is used, the downlink symbol can be configured from the first symbol position, and the uplink symbol can be configured from the last symbol.

Exemplarily, in the case where the center frequency of the uplink frequency domain resource coincides with the center frequency of the downlink frequency domain resource, taking the unknown time-frequency resource shown in FIG. 5a as an example, the GP can be configured on the thirteenth symbol; In the case where the center frequency of the uplink frequency domain resource does not overlap with the center frequency of the downlink frequency domain resource, taking the unknown time-frequency resource shown in FIG. 6 as an example, the GP is also usually configured on the thirteenth symbol.

In addition, two GPs can also be set in the format of the time slot. In this case, in order to satisfy the requirement that these two GPs are configured in the unknown time domain resource between the downlink symbol and the uplink symbol, optionally, the indication information is indicated when In the format of the slot, the time slot is divided into two parts: the first part and the second part for indication. Taking the indication information as the index number as an example, assuming that the number of symbols included in the first part is the same as the number of symbols included in the second part, then The corresponding relationship between the index number and the format of the time slot may be as shown in Table 6.

Table 6

Taking a time slot including 14 symbols as an example, the first part includes 7 symbols, and the second part includes 7 symbols. If the positions of the downlink symbols and the positions of the uplink symbols in the first part and the second part are pre-configured, they are all in accordance with the The first symbol position of this part starts to configure downlink symbols backward, and from the last symbol of this part forwards to configure uplink symbols, then when the index number is 1, the corresponding slot format can be as shown in Figure 8a, therefore, from Figure 8 In the format of the time slot shown in 8a, it can be seen that the position of the unknown symbol in the first part is between the downlink symbol and the uplink symbol, and the position of the unknown symbol in the second part is between the downlink symbol and the uplink symbol. The device does not need to send additional signaling to indicate the GP to the terminal device.

For example, when two GPs are set in the format of the time slot, the corresponding relationship between the index number and the format of the time slot may also be as shown in Table 7.

Table 7

For example, assuming that a time slot includes 14 symbols, the corresponding time slot format when the index number is 1 can be as shown in Figure 8b, in which the unknown symbol is divided into two parts, as can be seen from the format of the time slot shown in Figure 8b The position of the unknown symbols in the first part is located between the downlink symbols and the uplink symbols, and the position of the unknown symbols in the second part is located between the downlink symbols and the uplink symbols.

It should be noted that, three or more GPs may also be set in the format of the time slot in the above manner, which will not be repeated here.
